If you are not familar with the basic usage of Command Line Workstation (CLW), check out our getting started article. Let's say you have an agent that has been turned off. In this example, JVM2 has been turned off.
By default, Command Line Workstation does not include the ability to mount or unmount agents. However, the com.wily.field.clw_1.0.0.jar file can be added to <em_home>/product/enterprisemanager/plugins so that the unmount agents command can be used.
After com.wily.field.clw_1.0.0.jar has been placed in <em_home>/product/enterprisemanager/plugins, a restart of the Enterprise Manager is needed.
